Recent threads and posts are indicating that some of your trucks are going in for state inspections.
If you do the following you'll have a better chance at passing.
1. There should be no need to put the truck back to stock level 0.
2. Simply unplug and remove programmer and cable and go to test station.
If the above aren't followed and you put your truck back to stock level 0 you'll get a p1000 code and won't pass.
If you think you need to have the truck tested with stock programming than do it a week before and drive at least 50 miles before going to the test station.
